Police tailgating me

I was just driving on the freeway when I looked in my mirror and I see car lights about 4 feet away from my back bumper in a 110 zone. Keep in mind it was dark so I had no idea it was a cop, I maintained my speed in the right lane and he slowed down and sped up again but this time I wasn’t willing to take the risk of him getting so close so I sped up, from there he pulled me over and gave me a speeding ticket. Can I fight this in any way?
